JOSEPH AITBERS, OF ELLS, OREGON.

SPECIFICATION forming part of Letters Patent No. 395,804, dated January 8, 1889.

Application filed July 13, 1888. Serial No. 279,884. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH ALBERs, a citizen of the United States, residing at ells, in the county of Benton and State of Oregon, have invented a new and useful Improvement in Gates, of which the following is a specification. This invention contemplates certain improvements in gates, more especially for the passage of teams without requiring the dismounting of the driver, having for its object to provide for the ready opening and closing of the gates and the simultaneous unfastening or unlatching and opening of the same, as also automatically to secure the gates in their open position and to effect at one oper ation the release of the gates and the closing thereof; and the nature of the invention 0011- sists of mechanism for carrying out these ends, substantially as hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of my improved gate. Fig.

2 is a plan view of the same, partly in section;

and Figs. 3, 4, and 5 are enlarged detail sectional views thereof.

In the ap ilication. of my invention I employ, preferably, two gates, A A, of the construction shown, of which the hinging-posts a a are suitably pivoted in the has e or sill and overhead pieces I) Z) of a frame, B, braced in position. The gates A A are provided at their forward edges one with an edgewisedisposed. or vcri ical beveled plate, r, and the other with a keeperlate, c, to the forward ends of which are secured springs or snaps 0' 0 These springs or snaps are arranged in alignment with each other and project or extend outwardly and obliquely from the plate, their free ends standing opposite to each other and a short distance apart, to receive between them the beveled edge of the plate 0 to effect the holding together of the gates thereat.

C C are grooved disks or pulleys applied to the pivots at the upper ends of the hinging or pivoting posts a of the gates A A, and are provided upon their peripheries in the grooves with projections or stops d d, disposed to prevent the slipping or displacement of the chains or lines, presently referred to.

About at the center of the overhead piece I) of the frame B is an opening or passage, 11 immediately in alignment with which, upon the under side of the said piece, are secured and disposed two spring-plates or catches, d d. The catches or plates 11 d are bowed or inclined downward, their free ends standing a short distance apart and opposite to each other, to receive between them bevel'ended studs or plates (1 (1 applied to the upper ends of the forward end gate-bars, d cl.

D D are proppin or holding levers arranged above the overhead piece I) of the frame B, and having a common pivotal connection with one of two upright brackets or frame-like supports, 6, secured or mortised into the upper side of the said piece. This pivotal connection effected by the passage of apivot-bolt, 6', through apertures in said propping or holding levers and said bracket or frame-like support 6. The propping or holding levers D D are connected, by means of rigid links or short rods ff, with the spring-plates or catches d d, by means of which the action of the springplates or catches is further utilized to hold the propping or holding levers in their normal inclined position, as also to effect the dis engagement of the catches or spring-plates as the operatingdevers, referred to farther 011, are actuated, so as to open the gates. The propping or holding levers D,D are provided with pulleys g gone disposed in a slot or opening, g, in each lever. To the upper side of the overhead piece Z) of the frame B is fastened, intermediately of and standing partly in alignment with each of the propping or holding levers D, a beveled cleat, h, which serves as a stop to limit the downward and outward movement of the latter as their inner ends are moved upward, as will more fully appear hereinafter.

E E are two chains or lines operating and applied one to each pulley or grooved disk 0 of thegates. Those. portions of the two lines or chains E E upon the same side are passed under one pulley g of one of the proppinglevers D and have their ends connected together and looped upon a hook, g of one of two hand-levers, F F, suitably pivoted in the frame'like supports or brackets e. The opposite portions of the lines or chains E E are passed under the pulley g of the other propping-lever D and have their ends connected and looped upon the hook g of the opposite hand-lever F. This effects a connection be- 5 tween and permits of the actuation of the gate-pulleys, the props or levers, and the gateholding catches by means of the harul-levers. In order to effect synchronous movement of the gate-pulleys U C, they are connected to- IO gether by a connecting-rod,1 and crank arms or links 2" "L, which latter are fixed to said pulleys and to the ends of said connecting-rod.

The connecting-rod '1: is notched, as at to permit of the engagement therewith of the free or upper ends of the propping or holding levers D D when the gates are open.

In operation it will be seen that by depressing the outer end of either hand-lei'er F the chain or line E, connected therewith, will be drawn upon, which will simultaneously elevate or disengage the connected spring-plate or catch 1 from the beveled plates or studs (l d of the gates and rotate the pulleys C (l, which will swing open the gates, the opening action of the gate automatically effecting the disengagement ot' the plate cjt'rom the springplates or snaps c c at the forward edges of the gates. Upon the gates attaining their maximum extent of opening movement and the release of the hand-levers the connectingrod 2' will have been moved obliquely across the piece Z) of the gate-supporting frame l3 into position to permit of the engagement with one of its notches 2' of the coincident one of 3 5 the propping or holding levers D, which will thus prop or secure the gates in their open position.

In closing the gates, which is effected by the depression of the opposite hand-lever after 40 the passage of the team, it will be seen that simultaneously with such movement of said hand-lever the coincident proppin g orholding lever will be depressed or disengaged from the engaging-notch of the connecting-rod by the upward pull of the pulley-operating line or chain upon the coincident spring-plate or catch d, thus effecting the releasing of the gates from the holding levers or props and the closing or shutting of the gates at one operation.

gates, of pivoted opening-levers, connections between said levers and the pivots oi the gates, a rod connected to the pivots of the gates, and holding-levers operated by the pivoted levers and engaging the said connecting-rod, substantially as described.

2. The combination, with a pair of pivoted gates, of disks 011 the pivots of the gates, pivoted operating-levers, flexible connections between the said levers and disks, and pivoted holding-levers connected to the flexible connections, substantially as described.

3. The combination, wit-h a pair of pivoted gates, of disks secured to the pivots of the gates, a rod having its ends connected to the disks, pivoted operating-levers, pivoted holding-levers for engaging the said connectingrod provided with pulleys, and cords or chains connected to the said disks passing around and catches, substantially as herein shown and described.

The combination. of a pair of pivoted gates with a notched rod connecting pulleys en the gate, pivoting or hinging posts, and a propping or holding lever engaging said rod, substantially as set forth.

6. The combination, with a pair of pivoted gates, of a notched rod connecting gate-operatin g pulleys spring gate-locking plates or catches, and the propping or holding lever connecting with the spring plates or catches and engaging the said rod, substantially as described.

7. The combination, with a pair of pivoted gates and their operating-levers, of the gatepulley-operating lines or chains, a red 0011- necting the gate-pulleys, and the holding or propping levers limited in their outward downward movement by a stop suitably disposed and carrying pulleys, said lines or chains connecting the gate-pulleys and the operating-levers and passing up in contact with the pulleys carried by said holding or propping levers, substantially as specified.

8. The combination, with a pair of pivoted gates carrying pulleys at the upper ends of their pivoting or hinging posts and bevelended plates or studs at the upper ends of their forward edges, of chains or lines applied to and operating said pulleys and applied to operating levers, bowed or curved spring plates or catches, and the holding or propping levers connected to said spring plates or catches, said lines or chains passing up in contact with pulleys hung in said holding or propping levers, substantially'as set'forth.
